It highlights the challenges faced during the development process, such as ensuring precision in big or precise numbers for CSV and JSON downloads, and dealing with Excel's XML format and column references. The author also introduces two new npm packages: littlezipper, a Zip library that works across modern browsers, Node, and Deno; and xlsxtable, an Excel worksheet-writing library that depends on littlezipper.
